November 18, 2021
Planning a beta and not sure how many testers to recruit? This calculator turns what you know about your program into a tester count you can defend.
You tell it about your product type, cost, target market, audience source, and brand impact, and pick what you want to learn from the round. It recommends a range of testers, with the reasoning behind the number, using Centercode's methodology. If distinct groups in your audience need their own coverage, you can add them as segments.
What’s inside
Three testing objectives to choose
Pick bug detection, experience evaluation, or comprehensive validation. Your choice sets the baseline for your tester count.
Details about your program
Describe your product type, cost, target market, audience source, and brand impact so the recommendation reflects your situation.
A range, with the reasoning
Get a clear range of testers rather than a bare number, along with the thinking behind it.
Optional audience segments
